Cortical inactivation in behavioral tasks. A, Anatomical location of ferret auditory cortex and positions of cooling loops (blue) implanted in F1311 and F1509 and viral injection in F1706 over the MEG. A1, Primary auditory cortex; AAF, anterior auditory field; AEG, anterior ectosylvian gyrus; AVF, anterior ventral field; ADF, anterior dorsal field; PEG, posterior ectosylvian gyrus; PPF, posterior pseudosylvian field; PSF, posterior suprasylvian field; VP, ventral posterior auditory field. B, Distribution of cortical temperatures during bilateral cooling (all tasks) and unilateral cooling of left or right auditory cortex (sound localization only). Scatterplots show temperatures on individual trials measured at the base of each cooling loop, where contact was made with the cortical surface.
